We all like saving money, but sometimes it's hard knowing just when to pull the trigger. Thankfully, apps like Dealert by developer Kevin Foreman exist to help us keep tabs on the things we want. Dealert is a cross-site persistent price checker: you give it a product to watch for, and the Dealert service continually scours the internet for the best deal.

Not only does it find the deal, Dealert lets you share it, by give you the option to emails and text messages to yourself and your friends when you find an extraordinary deal. The latest update to Dealert brought Exhibition mode into the mix, so Dealert can passively show you what's up with your watched items. If you're looking to save money, Dealert's the app for you.

Contest: We have 100 copies of Dealert to give away. Just leave a comment on this post to enter. Contest ends this Sunday at midnight PST. Please only leave one comment, multiple entries won’t count. Promo codes are only valid on carriers serviced by the App Catalog, and users must be running webOS 2.1 or higher with the latest version of the App Catalog.

i like derek and all... but dude, you have to proof read your articles... they are super ridden with typos it's unreal. sure there are always some grammatical things you may miss, but give instead of given, in second paragraph... and the article before this, more typos. Dude, I really like you and your opinions, and you seem extremely bright, but the typos are too plentiful. A comment does not require much in grammatical precision, but an article, i think, deserves at least a once-over.

You should have capitalized I, Derek, and then I again. A comma required after typos. Your use of the word “sure” is not technically incorrect but shouldn’t be used to start a sentence even if it is in conclusion or in direct support to your previous sentence. Try using, “indeed” instead if you must begin your sentence like this or use “sure” following a semicolon to conclude your thought.

It’s annoying when someone spell checks your stuff isn’t it? I find it ridiculous…to me it doesn’t take away from the article. Maybe you should stop being so pretentious or go somewhere else that maybe meets the level of, “grammatical precision” you require.

I won the copy of flash cards in the last app giveaway but I didn't realize you have to be running webos 2.0 :(
I feel like I'm so behind everyone else with my pre minus. Are people leaving sprint to go get the Pre 2 or something?
I really can't justify leaving sprint for a new webos device. I'm paying $60 a month right now, for unlimited everything. If Verizon or AT&T could even come near this deal then I would switch but I can't justify paying $30 more a month just for having webos 2.0.

Awesome idea for an APP, but I would like also a multi-platform RSS kind of thing also. What if someone is gonna move away from WebOS or someone on another platform wants in on the deals? I am getting might tired of waiting and waiting for the illusive Pre 3 that's nowhere for sure...

Running the contest over so many days tells me that you're gonna choose the 100 winners at random after the Sunday deadline, right? Because others seem to think it was gonna be the first 100 that sign up. You never actually specify.
